JACOB J. HENZIE, OF DEEPRIVER, IOWA.

LOADING OR UNLOADING DEVIQ E.

SPECIFICATION forming part of Letters Patent 735,509, dated August 4, 1903.

Application filed April 13, 1903.

To all whom it may concern.-

Be itknown that I, JACOB J. HENZIEta citizen of the United States, residing at Deepriver, in the county of Poweshiek and State of Iowa, having invented certain new and useful Improvements in Loading or Unloading Devices; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters of reference marked thereon.

The present invention has for its purpose to provide a simple, strong, and efiective device for loading and unloading freight from a wagon'or other vehicle, whereby the teamster is relieved from anyefiort or physical exertion, thus facilitating the transfer of the load from the vehicle, which is rendered comparatively easy and without difficulty.

The invention consists in a loading and unloading device constructed substantially as shown in the drawings and hereinafter described and claimed.

Figure 1 of the drawings is a side elevation of my improved loading and unloading device, showing a wagon or other vehicle with a rack resting thereon and in position to be transferred to the device,the position of the vehicle, rack, and the position of the supporting-bars of the device being shown in dotted lines after the rack has been unloaded; Fig. 2, a perspective view of the loading and'unloading device.

In the accompanying drawings, A represents an ordinary wagon or other vehicle, upon which rests a suitable rack B,'by which the load is transferred from the vehicle to the dc vice, the rack being shown as one of many objects that are capable of use and is shown simply to illustrate the application of my invention in unloading the vehicle. I

Parallel supporting-rails C have connected thereto the .uprightposts D, and connected to the posts at their upper ends are bars E through the medium of the pivot-pins a, there by pivotally attaching the ends of the bars'to theends of the posts, so that said bars may be adjusted from a horizontal to an incline, as circumstances may require. The opposite ends of the bars E are rigidly connected to suitable hangers F, which hangers are ad- Serial No. 152,304.. (No 11 0 191.)

"justable in stationary guide posts G, said posts and the posts D being reinforced by diagonal braces H to strengthen the posts and prevent them from swaying laterally and holdingthe posts in a true upright position. The stationary guide-posts G have guidebrackets b at their top and bottom, which guide the hangers F in their vertical movement and provide braces to strengthen both the posts and hangers to better sustain the weight of the load upon the bars E. If preferred, the hangers F may have a. plurality of holes 0, and a pin is provided, as shown atf, suitably connected to the posts, so that the pin may engage the holes to hold thehangers in their adjusted position, or any other means may be provided to hold the hangers firmly in the position to which they are adjusted, as I do not wish to confine the invention to any particular means for attaining this end, and any changes or modification in the several details of construction may be resorted to without in any'manner afiecting the essential features of the invention or departing from the principle thereof.

Pivotally connected at d to the posts G are suitable fulcrum-levers I, which are designed to be operated by hand, said levers being connected at their pivotal ends to the ends of the supporting-bars E through the medium of rods J. The rods J are provided with eyes e at their ends to facilitate the attaching of said rods to'the supporting-bars E and the levers I, whereby apivotal connection of the rods is provided between the bars andlevers to enable the bars to be raised or lowered as circumstances require in loading or unloading.

It is evident that any suitable material may be used in constructing the device, such as wood or metal, and the several parts may be of any desirable dimensions as found preferable.

In the operation of transferring the load from thewag'on or other vehicle the sup-.

along between the bars E until the load is completely supported by the bars, after which the bars are raised to their normal position, the load being then suspended free from contact with the wagon or vehicle, as shown in dotted lines of Fig. 1 of the drawings. The suspension of the load above the bed of the wagon or other vehicle enables the wagon or vehicle to pass on between the bars and beyond the same.

Although I have shown a rack upon the wagon or vehicle to better illustrate the load ing or unloading of the same, it is evident that any object may be substituted in place of the rack, or the rack may be used to support the freight to be unloaded, such as farm products, as the loading and unloading device is the feature of the invention and not the rack or any part of the vehicle. The loading of the wagon or vehicle may be attained in substantially the same manner as unloading.

The device may be manufactured at a comparatively small cost, and it is both simple, strong, and durable and is efiective as a means for unloading freight from a vehicle without any material exertion to the driver or other person handling thefreight, and as there are comparatively few parts to the device there is consequently less danger of.

getting out of order or breakage from ordinary'nandlingor otherwise becominginoperative.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A loading and unloading device comprising stationary upright posts, parallel supporting-bars pivotally connected at one end to said posts, hangers connected to the opposite ends of the posts, stationary guide-posts and guide-brackets thereon with which the hangers engage, suitable pivoted fulcrum-levers, rods connecting said levers with the supporting-bars, and suitable means for holding the bars in their adjusted position, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
